摘要
As a representative of hierarchy-based protocol in wireless sensor network, LEACH is an elegant solution for energy efficiency. However, LEACH still has some deficiencies such as the great cluster and small cluster coexist; unreasonable cluster head selection while the nodes have different energy; the node still consumes energy after the death of the cluster head. We propose a new energy-efficient LEACH-based protocol that employed cluster member threshold and merged the tiny cluster to avoid the great cluster and small cluster existing at the same time; estimated cluster head';s energy to reduce unnecessary energy consumption. Analysis and simulation results show that our proposed algorithm provides more uniform energy consumption among nodes and can prolong network lifetime compared to LEACH.
